Product Description

Black silicon carbide (C) is produced by petroleum coke, quality silicon sand and appended with salt in an electric arc furnace at high temperatures. The hardness and brittleness are lower than that of green silicon carbide. The materials are used to grind cast iron, non-ferrous metals, rubber, leather, plastic, wood, mineral rocks, etc. It can also be used to manufacture high-class refractory products.
